Table 8402.1.1 Footnotes <br /> For SI: 1 foot .=304.8 mm, ci .=coous insulation, int.= intermediate framll IUI <br /> a R-values are minimums. U-factors and SHGC are maximums. When insulation is installed in a cavity which is <br /> less than the label or design thickness of the insulation,the compressed R-value of the insulation from <br /> Appendix Table A101.4 shall not be less than the R-value specified in the table. <br /> b The fenestration U-factor column excludes skylights.The SHGC column applies to all glazed fenestration. <br /> "10/151/21.+3;8"means -10oo tir s ns tam Oh=the eesic rof_it a waft,orR-:15 on-the oontinuous <br /> insulation on the interior of the wall,or R-21 cavity insulation plus a thermal'break'between the slab and the <br /> basement wall at the interior of the basement wall. "10/15/21.+TB" shall be permitted to be met with R-13 <br /> cavity insulation on the interior of the basement wall plus R-5 continuous insulation on the interior or exterior <br /> of the wall. "10/13" means R-10 continuous insulation on the interior or exterior of the home or R-13 cavity <br /> insulation at the interior of the basement wall. "TB" means thermal break between floor slab and basement <br /> wall. <br /> d R-10 continuous insulation is required under heated slab(on grade floors.See IZ4.02.2.9, <br /> e There are no SHGC requirements in the Marine Zone. <br /> f Reserved. <br /> g Reserved. <br /> h Reserved. <br /> i The second R-value applies when more than half the insulation is on the interior of the mass wall. <br /> j Resented. <br /> k For single rafter-or joist-vaulted ceilings,the insulation may be reduced to R-38. <br /> I Reserved. <br /> m Int. (intermediate framing)denotes standard framing 16 inches on center with headers insulated with a <br /> minimum of R-10 insulation. <br /> Table R402.1.3 Footnote <br /> a Nonfenestration U-factors shall be obtained from measurement, calculation or an approved source or as <br /> specified in Section 8402.1.3. <br />
